Question

On a hot summer day, a pesky little mosquito produced its warning sound near your ear. The sound is produced by the beating of its wings at a rate of about 600 wing
beats per second.

What is the frequency in Hertz of the sound wave?

Assuming the sound wave moves with a velocity of 350 m/s, what is the
wavelength of the wave?

Answer 1

Explanation:

On a hot summer day, a pesky little mosquito produced its warning sound near your ear. The sound is produced by the beating of its wings at a rate of about 600 wing beats per second.

Answer 2

Given - Rate - 600 beats per second

Velocity of sound - 350m/s

Find - Frequency and wavelength of sound wave

Solution -

Frequency is referred to as number of beats per second.  Hence, rate of beating will be the frequency. Therefore, frequency will be 600Hz.

To calculate wavelength,  formula to be used will be -

V=f*lambda

V is velocity of wave,  f is frequency and lambda is wavelength.

Keeping the values in equation,

Lambda = 350/600

Lambda = 0.58 m

Hence,  frequency of wave is 600 Hertz and wavelength of wave is 0.58 m
